INKING MECHAN ISM.

Specification of Letters Patent.

Application led J'une 25, 1908.

- To all whom it 'may concern:

, invention' as adapted particularly for ad- -dressing machines in which printing devices,

consisting l/ of platesy bearing addresses stamped'in relief thereon or frames carrying type forms, are run through a machine for printing the address on 'envelops, letters, etc.

The object of the invention is to apply the ink evenly and uniformly on the face of the printing characters, and to avoid apply.- ing the ink elsewhere on the printing devices.

yA further'object of the invention is to rovide for automatically feeding the inkmg rolls endwise to avold uneven wear of the face thereof.

The -invention has other objects in View which lwill a pear hereinafter in a detail description o the accompanying drawings which show one embodiment of the invention and in which` Figure lis aside elevation showing the invention with as much ,of an addressing machineas is necessary. Fig. 2 is a transverse sectional view through the ink fountainand its roll. Fi 3 1s a detail transverse sectional view-t rou h the plate -carrier frame and showing t e-position of a printing plate relative to the rolls. Fig. 4 1s a ,top plan. view of Fig. 1. Fig. 5 1s a detail view, partly in section, showin the means for feeding the ink rolls en wise.

In the drawin s 6 desi ates a carrier which is arrange to trave in a frame 7.

The carrier, as shown, consists of'a pair of sprocket chains which are provided at interwith blocks 8 or other suitable devices forp'ushing the printing devices 9 through the inking mechanism.

A main frame 10 is supported in any suitable manner and a driving shaft 11 1s journaledv in said` frame and carries a sprocket -wheel 12 over which travels the Iroll 25 and both inkin driving sprocket chain 13, the latter being driven by any suitable means.

A yielding frame 14 is pivotally mounted at one end on a rod 14 which is supported in the main frame and the other end of this ylelding frame is bored at 15 to receive a post 16 which is mounted on the mainframe. A spring 17 is arranged on the post 16 above the frame 14 and is held in place by a nut 16.

A post 18 is mounted on the frame at each side thereof and bearing blocks 19 are movably arranged on these posts. Inkingr 'rolls 20 are mounted on shafts 20', 20 which are journaled in said bearing blocks. A spring 211 is arranged on each ost 18 above the bearin block 19 and be ow the nut 21. Each gearing block is rovided with projections 19 at its ends, an `adjusting screws 22 are secured 'm said projections Iand arranged to bear upon the mainframe.

By adjusting the screws 22 the inking rolls 75 are properlyy positioned to apply ink to the printing devices which are moved thereunder and the springs 21- hold the inkingrollsyieldingly in this position. A fountain frame 23 isfalso, mounted on the rod 14 and made fast to 'the yieldingframe 14b pins 23. This fountain frame is provide .with a well 24 to receive the ink and a fountain roller 25 is mounted on a shaft 25 in said fountain frame. A scraper 26 is fastened to a support 26 which is pivotall mounted on a rod 26" in the fountain rame, the scraperbeing arranged to engage'theV fountain roller 25 tangentially and remove surplus ink therefrom. This scraper isadjusted relative to the fountain roller b means of an eccentric 27 which is o erated y a handle 27 and engages a de en ing projection on the support 26. y operating the ceceni tric .the scraper may be caused to 91SV with more .or less pressure, as required', against the fountainv roller.

A. transfer roll 28 is mounted on a shaft 28 ijournaled inthe yielding frame. This roll is arranged to contact withl the fountain 100 rolls 20, and it transfers the ink 'from e fountain roll to the inking rolls. A gear 29 on the shaft 11 meshes wlth a'gear 30 on a. shaft 30' which carries a roll 31. The gear .30 meshes with 105 a gear 32 on shaft 2G and the latter gear the meshes with a gear 33 on shaft 28', The latter gear 33 meshes with a gear 34 on shaft. 25 and also with a gear 35 on shaft 20 and the latter gear 35 meshes with a gear 36 on a shaft-36 which carries a roll 37. The gear 29 also meshes with a gear 38 on a shaft 38.l which carries a roll 39 and the latter gear 3,8 meshes with a gear 40 on shaft 40 and this gear in turn meshes with a gear 41 on shaft 41 which'carries a roll 42. The shafts 30, 36', 38", 40 and 41 are suitably supv ported in the main frame 10. The gear 38 also meshes with a gear 43 on a shaft 43 which carries a roll 44 and the gear 41 also meshes with a gear45 mounted on a shaft 45 which carries a rollv 46.` The shafts 43 and 44 are supported in `bearing blocks 47 which are adjustably arranged on posts 48 mounted 4on-the main frame, one at each side thereof. These bearing'blocks 47 have projections 47 and adjusting screws 49 operate through said projections and bear upon the main frame.. Springs 50 are arranged -`on posts 48 above the bearing blocks 47 .and beneath thev nuts 50. It will beobservedthat the distributing or evening rolls 44 and 46 are capable of adjustment relative to the printing devices and are yieldingly held to bear upon the printing devices in a `manner similar to the inking rolls 20. The rolls 37, 31, 39 and 42 are made of steel or any other material to-.forma support for the rinting devices and they are located immeiately below the 'inking and distributing rolls. The inking rolls .and the distributing rolls are provided with a facingof felt or rubberfor othervyielding 'material and the transfer and -fountain .or supply rolls are preferably made of steel, although I do not limit myselfto any particular materials.

The shaft'28 is provided with a worm 51 whichvmeshes with a worm gear 52 on a vertical shaft 52" suitably supported in the yielding frame 14. A lever 53 is pivoted at 5 3 on' one ofthe bearing kblocks 19 and the ends of this lever 53 rest in peripheral grooves 54 foried in any suitable manner on'the shafts 20 and 20". An eccentric 55 on the lower end of shaft 52 is arrangedv too erate in an endwise groove 56 at one end o the lever 53. It will be readily understood that -as the vertical shaft 52 is rotated/the eccentric disk 55 working in the yslot 56 will'swing the lever 53 on its ivot v.53', and lthe en ds of said lever will shi 'the lnkinmlls endwise and alternatelyinopposite tio/ns. the printing devices travel ina certain'v ath through` the inking meclaanismqand'asA t e lines of type are. generally'arranged in a certain position on the printing devices it would naturally follow.

that the l e would constantly en age the saiul'face. the inking rolls at or aout the same place and wear these rolls unevenly if n0 means were-provided for adjusting the rolls endwise.I By means of this endwise adf j ustment of the rolls uneven k.Wear thereof is avoided .and they are .for this reason better adapted to apply the ink evenly to the'type characters.

lTo facilitate the adjustment of the eccentric 27 to secure the proper position of the scraper relative to the fountain roll I mayl ported so that they will yield as may be required.
